• Description

Create an Ideal Weight application that accepts input for:
- A person's name
- A person's height
-The system of measurement they wish to use (metric or imperial).
The program will use the person's height to calculate his/her ideal healthy weight using a formula produced from the formula for body mass index (BMI). The BMI is a statistical measurement which compares a person's weight and height.
Though it does not actually measure the percentage of body fat, it is a useful tool to estimate a healthy body weight based on a person s height. According to the BMI, a value of 18.5 to 25 is considered healthy.
In this program, allow the user to use either the imperial measurements or metric to calculate a healthy weight.
Metric: Weight (kg) = height (metres) × height (metres) × 25
Imperial: Weight (pounds) = height (inches) × height (inches) × 25 ÷ 703
